'Another objectfin providing two "inde pendent sockets' and'trunnions, asetfor each car, is topermit the removal' of either car from the truck without interfering with the continuance of the other car on the truck.

Another object'n dividingthe weight of the two' cars between the twog'sets of sockets` andv trunnions is togprevent overloading either set of sockets and trunnions, which s me to carry into'eifect, isf-that:

"far: t f bo ster; and` iof Amy 'invention' is 'the iotherwiswould exclude thefe'ntrance of a pivotl sockets num" `r l1 i vdijca'tes the carplatforms 2of twofadjacent which are. tobe pivot- "rn'oun'ted'n orjarticulated on a common 2 afsingle truck1 vwhose Whels are' indicatedat 3.

Ellis, filed the 145th vday'of` December, 1923, Serial No. 680,603, Referring now to the double articulation, see particularly Figs. 2 and 3 where a base plate (,Ypreferably in the forrnof a heavy casting,` 'is shown secured to thebolster 2.. This plate is provided with semispherical sockets 8, adapted to receive simila'rlyshaped pivot trunnions. Theseare indisclosure cation of dicated at 9, and are'formed as a. partof a eneral trunmonplate thebody of which is mdicat'ed'at 10.', To each car platform is -secured in' any convenient way, one of these trunnion lates, theoutline of which is shown in otted lines in Fig. l.'

Thus it willl be seen that each of the two 'adjacent cars is supported by its own otal 'connection with the same common lster of a truck allotted to the function of sustaining andcarrying the adjacent ends referred `of two cars.

In order to fprevent" thefaccidentalA .dis-

which fits within recesses or over shouldelTS shown at 13. There is 4suiiicient space left between the bolt and vthev shoulders tao-admit of the required movementofthe trunnions in actingas pivots, yet the relation of the bolt to the trunnions is such that -the latter cannot bethrownout oftheir, sockets by .reason'of the 'up and down vibrations-of the cars,` orin case. of accident. This boltf12 is removable so'that either or bothftrunnions. maybe removed from, the sockets as fdesired',

'asinmakingirepaiison thecars. y y "It will'be observed also that by reason of thetrunnionpivots beingA independent, either:

may be removed for purposes of re airing o r otherwise 'workingfgjon one ofA t e cars' Withqutfll pxpesnse, and necessity'of applythe o erfc'ar 'as to which no repairs are Aneeded;

Anotherffeaturefof; vadvantage -and -utilityf'v the of the double trunnions is that,

' eachhas' tocarry the weight of .one car lso .j

Athat its contact with-fthe socket not eo ".ffjgreatae to excludethe' ready'entrance of a ubri'cant, whereas ifftheweight of both carsv were all placed upon a single ivot trunniori Vitwould result inv excluding t e application of the lubricant due to the excessive weight,

asIh'ave found -in practice; n

It will 'now' be seen thatby reason of the double or'plurarelitly of pivot trunnions, the two cars may f y articulate to accommodate their constant y changing relative po sition, `for' instance, fjwhen they reach .the

crest of the hill with one car on one slope on one side of the crest and the other car `on the other slo at the other side, at which time the wi Vform an obtuse angle.- Then again, w en-they reach 'fthe di of a hill and come to the dip'between two ills, they will freely'articulate so that one car will incline upward on one side of the dip and the other incline downward on the ot er side of. the

. di lihen again, when the cars change their lateral relative position as when going ro'undv a. curve and 'at the same time vhave reached the crest'of a hill, one cat .on one side and the other car onthe other side of such crest or have reached the di'p between twohills with one ca r travelling downwardlon the hillside while theether car is trav'e ing upwardly, the" will be free te more and assume diierent re ative positions laterally andialso other.
